APPARATUS FOR CEMENTING THE CHANNELS F BOOT OR SHOE SOLES;

SPECIFICATION formingpart of Letters Patent No. 278,086, dated May 22, 1883.

Application filed March B, 1883.

siding at Lynnfi'eld, in the county of Essex and State of Massachusetts, have invented certain new and useful lmproveinents in'Machines for Oementing Channels in Boot or Shoe Soles; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of reference marked thereon, which form a part of this specification.

This device is intended to perform the labor of smearing with cement the channels of boot or shoe soles; and it consists of a device containing the following elements: a reservoir to contain the cement for smearing the channel, and an air-pump for charging the fountainbrush for applying the cement to the channel of a sole, connected with the interior of the cement-reservoir by a flexible pipe to permit ot' freedom of motion of the brush in any direction.

The drawing accompanying this specification represents a sectional elevation ot'a device embodying my invention.

In said drawing, A represents a reservoir or tank in the form of an upright can, erected or supported upon a suitable base, B, this can being intended to contain a quantity of cement suitable for cementing the channels of boot and shoe soles, this can, when supplied with cement, being never entirely filled, in order that an air-space may remain above its contents.

0 represents an air-pump of any ordinary construction, the same communicating with the upper part of the can A by a pipe, D, in order that the space a above the cement may be filled with compressed air from the pump, a cock, I), being placed in the pipe D for the purpose of relieving the pipe D from effects of pressure, and preventing leakage of air from the can by way of the pump. At the bottom of the pipe D, I have placed an air-drum, F, provided with a check-valve, f, to facilitate the process of pumping and lessen the chances of leakage and back flow of air upon the P P- E in the drawing represents a flexible pipe,

(No model.)

| one end of which communicates with the lower part of the can A, while its opposite end is furnished with a fountain-brush, c, for distribution of the cement from the can.

In the operation of this device the can is supplied with the requisite quantity of'cemcut-say about five-sixths full-and the cock I) opened. The operator now operates the pump 0 and fills the upper part of the can with compressed air to the desired pressure, and closes thecock b. The operator now seizes the brush, which is constantly supplied with cement from the can by the pressure of air in the latter, and proceeds with the operation of smearing the channels of boot or shoe soles until his labor for the time is completed, when he closes a cock, d, in the pipe E and shuts ofl' the flow of cement to the brush. As the can becomes exhausted of its supply of cement it is to be refilled and the operation of supplying air repeated.

Heretolore in the operation of cementing the channels of boot or shoe soles it has been customary for the operator to simply employ an ordinary brush, which he from time to time dips into a vessel of cement and transfers cement from the latter to the channel. In this manner of proceeding the operation is comparatively lengthy and inconvenient, and considcrable cement is spilled about and wasted.

By means of mydevice thelaborofcementing channels is performed with expedition, ease, and economy, and no cement is spilled or wasted. A secondary cock, 0, may be located to the rear of the brush and further regulate the supply of cement thereto when in active operation.

I claim In an apparatus for cementing the channels of boot or shoe soles, or other analogous purposes, the combination, with a reservoir for holding the cement, of an air-pump arranged to charge the reservoir above the cement with compressed air, a flexible pipe for conveying the cement, and afountain-brush, all arranged substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.
